Benefits of technology

The patent relates to a device and method for creating anastomoses, or connections, between two hollow organs. The goal is to provide a simple tool that can produce high-quality anastomoses.

Problems solved by technology

However, the tolerability of these sealants or glues is problematic because they may exhibit thrombogenic and toxic properties.
The disadvantage of these clamping techniques is that they generally remain in the hollow organ to be connected and can trigger rejection reactions and there is also danger of the formation of a thrombus.
One problem of the technique described in WO 03 / 061487 A1 is that the produced connections are frequently not sufficiently stable.

Embodiment Construction

[0041]In the description hereinafter, the same reference signs are used for the same parts and for parts having the same function.

[0042]FIG. 1 shows an adhesive applicator 10 that can be detachably connected to a device for producing anastomoses, e.g., an electrosurgical instrument 1 (FIGS. 4 through 8).

[0043]The adhesive applicator 10 includes an adapter 19 with adhesive capillaries 12, 12′, a feed pipe 18, and a coupling piece 20. The coupling piece 20 represents the proximal end of the adhesive applicator 10, whereby the coupling piece 20 is connected with the adhesive capillaries 12, 12′ via the feed pipe 18 and a feed line 17. The coupling piece 20 may be Y-shaped and includes an adhesive connecting orifice 21 and a propellant connecting orifice 25. Via the adhesive connecting orifice 21, an adhesive can be introduced into the feed pipe 28. A propellant may be pumped into the feed pipe 18 via the propellant connecting orifice 25 in a time-delayed manner driving the adhesive thr...

Abstract

A device for producing anastomoses between a first hollow organ and a second hollow organ including a sheath and an adhesive applicator that can be positioned next to the sheath in order to apply an adhesive to the adhesive bonding section. A method for producing anastomoses between a first hollow organ and a second hollow organ includes folding the first hollow organ over a sheath, positioning the second hollow organ over the first hollow organ, producing a first connection between the hollow organs by applying a high frequency (RF) voltage, and producing a second connection between the hollow organs by applying a tissue adhesive.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to PCT / EP 2010 / 004259, filed Jul. 13, 2010 and published as WO 2011 / 006639, which claims priority to DE102009032972.2, filed Jul. 14, 2009.FIELD OF THE INVENTION[0002]The disclosed embodiments relate to surgical instruments, and more particularly to surgical instruments used to form anastomoses.BACKGROUND OF THE INVENTION[0003]An anastomosis is a connection between two anatomical structures. For example, in the course of an organ transplantation, severed blood vessels can be connected with each other by means of anastomoses.[0004]Various methods for producing such anastomoses in surgery are known. The connection can be produced with the use of suturing techniques. Furthermore, there are approaches that allow the organic connection with the use of adhesion techniques. In one example, fibrin sealants are used, thus making possible the highly advantageous connection of organs, in particular hollow organs. How...
